'HARROW.

S?EOIFIGA'1ION forming part of Letters Patent No. 440,854, datedNovember 18, 1890.

Application filed August 19, 1890- Serial No. 362,386- (No model.)

To all whom it may concern.-

Be it known that I, EDWARD J. TRAVIS, a citizen of the United States,residing at Paris, in the county of Henry and State of Tennes= see, haveinvented new and useful Improve= ments in Harrows, of which thefollowingis a specification.

I have produced a harrow for farm use constructed of blocks providedwith teeth and connected together so as to break joints and form aflexible triangular-shaped platform in which the blocks have acompactabutting relation and have a runner-like action upon the ground, andform a platform having a practically solid bottom and top surface Welladapted for crushing the lumps of dirt and leaving the surface smooth,and for this purpose can be used on its untoot-hed side. The blocks areflat and are beveled upward at their forward under sides, and they areof diamond shape and connected by wire rods so that the nose of eachblock will abut against the beveled rear sides of the contiguous blocks,to keep them all close together laterally and give a solid runningaction to the harrow while allowing it to conform to the unevenness ofthe ground.

The improvement will be particularly pointed out in the claims, inconnection with the accompanying drawings, in which-- Figure l showsmyimproved block-barrow in top View. Fig. 2 is a vertical longitudinalsection of the same. Fig.3 is one of the beveled blocks with surfacefastening-eyes. Fig. 4 shows abeveled block bored at each end for thefastening-wires; and Fig. 5 shows the blocks connected by surface rodsand eyes.

The blocks a are of diamond shape, preferably made sharper at thenose 1) than at the heel c, and are beveled u pward at the nose end onthe under side at s, so that they can be connected together in compactabutting relation at each end sidewise and have a runner-like action onthe ground. I connect these blocks in rows with their beveled noses bstanding forward between and abutting against the sides of the heels 0of the next row of blocks, so as to bring them compactly together andform a platform of solid blocks. I connect them together at each end bystoutwire rods d, which I prefer to run across their upper sides andfasten to the block by eyedscrews 0 or rivet staples, or I may run thefastening-wires through holes f in each end of each block, as seen inFig. 4. The flat blocks, when connected, form a solid-bottomed platformwell adapted for crushing the lumps of dirt and leaving the surfacesmooth. While the fastening-wires may be rigid from end to end, yet Iprefer to joint them, as at g, along the middle line of the harrow toallow it to flex sideWise, While the fastening-Wires allow it to flexendwise and to be folded or rolled endwise for turning short curves. Theblocks may be provided with any suitable form of barrow-teeth h andarranged as desired; but I prefer to use the bent and twisted toothshown, having their fastening-shanks i secured in recesses j in thebottoms of the blocks, so that the latter will more easily ride over thesurface of the ground.

The harrow may be turned over upon its back in going to and from thefield, and it may be thus used for smoothing the surface by the flattops of the-blocks riding upon the surface as a fiat board having anunbroken surface.

I claim as my improvement-= 1. A flexible harrow composed of flatdiamondshaped toothed blocks arranged to break joints with each other,provided with teeth and connected together at their ends in rows,forming both a harrow and a crushingplatform, as shown and described.

2. A flexible harrow composed of fiat diamond-shaped toothed blocksarranged in rows to break joints, beveled upward on their under forwardends, and connected together at their lapped ends, as set forth.

3. A flexible harrow composed of fiat diamond-shaped blocks providedwith teeth and arranged to break joints with each other, each blockbeing fastened together by eyed fastenings and wire rods on their uppersides, as shown and described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing ALEX. 13. WHITE, W. E. WELDoN.
